Why is it not available inside a reel?

Upstream it expects @Image tags in the prompt to point at each reference, and our prompt compiler has no Grok dialect yet — it would emit prose with no tags. Whether the references still apply without tags is unverified, and reel is the wrong place to find out, since a character swap there is silent. It is fully available on the standalone video tool.

What resolution does it output?

480p or 720p. If you need 1080p or 4K, Kling V3 and Veo 3.1 go higher.

Grok Video or Hailuo 2.3?

Grok is cheaper and takes seven references against Hailuo's one. Hailuo reaches 1080p. For reference-driven work Grok, for a clean single-subject shot at higher resolution Hailuo.

Grok Imagine Video

Grok Imagine Video is xAI's video model. It accepts up to seven reference images — more than most models here — while costing less per clip than anything else we publish. For volume work where every shot does not need to be a hero shot, that combination is hard to argue with.

Lowest Cost Per Clip

Cheaper than Hailuo 2.3, which had held that position. For a reel where most shots are establishing or cutaway, the saving compounds across the board.

Seven References

More than Kling V3 or Vidu Q3 accept. Useful when a shot has to carry several distinct subjects at once.

Verified on Both Providers

The reference field is named differently on each — reference_image_urls against image_urls — but both document the same semantics and the same cap, so a request carrying references can move between them.

ModeloHailuo 2.3Hailuo by MiniMax produces highly aesthetic, stylized video content with a distinctive cinematic look. Known for beautiful color grading, smooth motion, and artistic flair that makes every output feel professionally directed.

ModeloVidu Q3Vidu Q3 generates video from reference images rather than from a single start frame. That distinction is the whole point in a reel: a start-frame model only knows what shot one looked like, while Vidu is handed the character sheet itself and can therefore keep that person recognisable in a shot it has never seen.

ModeloGrok ImageGrok Image is xAI's text-to-image model, available here on both of our providers. It sits at the cheap end of the catalog without being a draft-quality model, which makes it a reasonable default for boards you expect to iterate on rather than keep.
